Letters Patent No. 110,100, dated December 13,1870.

IMPROVEMENT lN WElGHlhlG-WAGONS.

The Schedule referred to in these Letters Patent and making part of the same.

I, GEORGE A. W1Lcox, of Chicago, in the county of Cook and State of Illinois, have invented certain Improvements in Scale-\Vagons, of which the following is a specification.

My invention relates to a wagon constructed so that the contents may be weighed by a scale attached thereto.

'The box of the wagon is so constructed that, at pleasure, it may be hoisted clear of the bolsters and running-gear by means of alevcr or steelyard, which has its fulcrum in an upright standard, said standard being supported upon the running-gear of the wagon, and passing up through a tube or \\'ell-hole vertically at about the center of the wagon-box, as will presently.

be set forth more explicitly.

in the accompanying drawing, which, together with the letters and figures of reference marked thereon, form part of this specificationl igure 1 is a side elevation of a wagon constructed aftermy invention.

Figure 2 is a plan or top view of same.

Figure 3 exhibits a side elevation of same in the act of dumping or discharging the load.

Figure 4 is a side view of the detachable or supplementary bolsterhereinafterreferred to.

General Description.

Upon the axle-trees of the wagon I place the detachable bolster A, having upon its under side two pins or dowels, a a, and at the center of the upper side a conical pivot, a. These bolsters are two in number-one for the front and one for the rear axle.

Attached to the rear axle are the two parallel reaches B B, extending forward nearly to the front axle, where they meet and are secured to a prolongation of the fifth-wheel O.

At about the center of the wagon is the transverse supportor beam D, which is firmly attached to the reaches B B E is the wagon-box. At about thecenter thereof is the vertical tube or well-hole F, the purpose of which is to surround an opening, G, through which passes the vertical standard H. This standard rests in a socket in the beam D.

The said standard has, at its upper extremity, a crotched bearing for the pivot or fulcrum i of the steelyard I.

J is a cross-piece, attached to the wagon-box, carrying the link or staple The steelyard I has, at its short arm, a hook, 7:, adjusted to catch under the link j.

The wagon-box may be lifted clear of the runninggear by means of this lever or steelyard I, and the load may be weighed by a plumb or weight arranged to slide upon the said steelyard. But, as the weights are likely to be great, I arrange a second lever, L, of the second class, connected to the lover I by the rod 1. Upon this lever L I make a graduated scale and place the plumb or weight.

M is a swinging support, pivoted to the under side of the rear axle at m, and carrying the'lever L, pivoted, at a, near its free extremity.

\Vhen not in use, this support, after detaching the rod 2 from the lever L, may be swung around under the axle out of the way, carrying the lever L with it.

After the load is weighed, and while the box still swings clear of the running-gear, I remove the .detachable holsters A A and allow the box to come down until it rests upon the rollers 71 t, one pair of which, i, is attached to and has a bearing upon the box, while the other pair, i, has a bearing upon and is attached to the reaches B B.

These reaches B B are grooved at their upper surface, to afford a guideway for the rollers i.

The vertical standard H may now be removed, and with it the steelyard I.

The box E, containing the load, may be thus easily rolled back until the stop P catches against the rear axle, when the weight of the load will ordinarily be sutticient to tilt it and discharge the contents, as seen clearly at fig. 0.

One of the principal advantages of my scale-wagon lies in the fact that, when not actually engaged in weighing, there is no wear upon the weighing appa ratus.

I dispense with the complicated system of balancelevers, and, consequently, with the liability of breakage and wear in thepivoting attendant thereon.

Clams.

Having thus fully described my invention, \Vhat I claim an new, and desireto secure by Letters Patent, is

1. The arrangement of the lover or steelyard I, with its attachment, to the wagon or cart-box at a point above the center of gravity of the same, for suspending it for weighing, as specified.

2. The combination of the wagon-box 15, having the tube or well-hole 1?, with the standard H, supported'upon therunning-gear, and the lever or steelyard I, substantially in the manner and for the purpose set forth.

3. The combination of the wagon-box E, the tube F, standard H, steclyard I, lever L, and pivoted bar M, substantially as and for the purpose set forth.
